Summary
This study is testing whether an artificial intelligence program can detect chronic obstructive pulmonary disease (COPD) by analyzing cough sounds recorded on a smartphone. Researchers will collect cough recordings and medical data from 3,000 adults in China, both with and without COPD, to train and validate the AI model. If accurate, this could offer a low-cost, non-invasive screening option for COPD, especially in primary care settings where standard breathing tests are not available.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- artificial intelligence analysis of cough sounds
- What this could lead to
- If successful, this could provide a simple, affordable way to screen for COPD using just a smartphone recording, especially in places without access to standard breathing tests.
- What could go wrong
- The AI model is still being developed and validated, so its accuracy in real-world settings is not yet proven. The study is limited to one region in China, so results may not apply elsewhere.
